摘　　要：介绍了河南省叶县滑石矿的矿物成分、化学成分、粒度分布及自然白度特征 ,依据矿石中圆度不等的白云岩砾石和未固结成岩等特征 ,确定其为一第四系搬运沉积型矿床 .论述了叶县滑石矿的重力选矿、漂白除铁工艺流程及主要技术参数 .依据GB1 534 2 94标准 ,该滑石粉可用作造纸填料、陶瓷原料 ,基本达到了微细滑石粉的质量要求 .It has introduced the mineral and chemical composition, the grain size distribution and the natural whiteness feature of the talcum mines in Yexian county of Henan province. On the basis of the feature of the un_consolidation diageness, it has determined that it belongs to the 4th transport sedimentary mineral deposits. It has stated the gravity benefaction, the technique process of the bleaching defecation and its main technical data. According to the standard GB15342*.92, this kind of the talcum can be used as the fillers of the paper_making, the raw materials of pottery and porcelain and its quality can satisfy the requirement of the tiny talcum powder.
